Touchpad device and method for generating touchpad information

Abstract

A touchpad and a method for generating touchpad information are provided. The method includes: performing by a controller: in response to detecting that a first touch object is located in a sensing region of the touchpad, determining whether or not a specific touch event is identified; in response to determining that the specific touch event is identified, determining whether a second touch object is located in a first predefined region of the sensing region, and determining whether the second touch object is a predefined object; in response to determining that the second touch object is located in the first predefined region and the second touch object is the predefined object, reporting first touch information and second touch information to an operation system. The first touch information indicates that the second touch object leaves the sensing region, and the second touch information indicates that the specific touch event occurs.

1 . A method for generating touchpad information, comprising:
 performing, by a controller connected to a touchpad, following processes:
 in response to detecting that a first touch object is located in a sensing region of the touchpad, determining whether or not a specific touch event is identified; 
 in response to determining that the specific touch event is identified, determining whether a second touch object is located in a first predefined region of the sensing region, and determining whether the second touch object is a predefined object; 
 in response to determining that the second touch object is located in the first predefined region and the second touch object is the predefined object, reporting first touch information and second touch information to an operation system, 
 wherein the first touch information is used as masking information to simulate that the second touch object leaves the sensing region, and the second touch information indicates that the specific touch event occurs. 
   
     
     
         2 . The method according to  claim 1 , wherein the specific touch event is a click event, and in response to determining that one of a single-tap event, a physical-click event, a tap-to-click event, and a corner-tap event occurs, the controller is configured to determine that the specific touch event is identified. 
     
     
         3 . The method according to  claim 1 , wherein the predefined touch object is a non-finger object, and the first predefined region includes a first sub-region located at a lower right corner of the sensing region and a second sub-region located at a lower left corner of the sensing region. 
     
     
         4 . The method according to  claim 1 , wherein, in response to determining that the second touch object is detected but not in the first predefined region or the second touch object is not the predefined object, the controller is configured to report the second touch information and third touch information to the operating system, wherein the third touch information indicates that the second touch object contacts the sensing region. 
     
     
         5 . A method for generating touchpad information, comprising:
 performing, by a controller connected to a touchpad, following processes:
 in response to detecting a first touch object and a second touch object are located in a sensing region of the touchpad, determining whether the first touch object and the second touch object are respectively a finger object and a non-finger object simultaneously appearing in the sensing region; 
 in response to determining that the first touch object and the second touch object are the finger object and the non-finger object simultaneously appearing in the sensing region, reporting first touch information to an operation system indicating that the first touch object contacts the sensing region and not reporting to the operation system that the second touch object contacts the sensing region. 
   
     
     
         6 . The method according to  claim 5 , wherein the process of not reporting to the operation system that the second touch object contacts the sensing region includes reporting second touch information to the operation system indicating that the second touch object leaves the sensing region if the second touch object was reported as contacting the sensing region before reporting the first touch information. 
     
     
         7 . The method according to  claim 5 , wherein, after reporting the first touch information, further reporting fourth touch information to the operation system indicating that the second touch object contacts the sensing region. 
     
     
         8 . The method according to  claim 7 , wherein the fourth touch information is reported after the first touch object left the sensing region.
